Cook heads to DL, other medical news

The Rockies placed pitcher Aaron Cook on the 15-day disabled list with right shoulder on Satuday, a day after he left a start against the Giants after facing one batter in the fourth inning. But Cook’s situation is still shrouded in uncertainty. The Rockies will know more after seeing the results of Cook’s MRI on Monday.

Rockies manager Jim Tracy said Cook could be looking at something similar to the shoulder strain that left-hander Franklin Morales suffered early in the season, which could mean 3 1/2 weeks. That would mean the Rockies could be without their veteran starter until the middle of September, which is not exactly the prescribed way to fight for a playoff berth. As for Wednesday’s start against the Dodgers, Tracy confirmed that right-handers Adam Eaton and Josh Fogg are in-house candidates.

To replace Cook, the Rockies called up right-hander Matt Herges from Colorado Springs. Herges was one of the bullpen leaders during the 2007 run that landed the Rockies in the World Series. He began this season with the Indians.

In more positive medical news, shortstop Troy Tulowitzki returned to the club Saturday after spending much of Friday vomiting because of a bug he had. Tulowitzki is in the starting lineup, but the Rockies will keep a close eye on him.

But in a more ominous development, right-handed reliever Manuel Corpas, currently out after undergoing surgery to remove a bone chip from his throwing elbow, revealed that he underwent another surgery 10 days ago because of an infection in the forearm of that same arm.

To make room on the 40-man Major League roster for Herges, the Rockies moved Corpas to the 60-day DL.

After the arm and fingers swelled, doctors checked for other bone chips. Corpas has a device through which he is being administered antibiotics every 10 hours. Corpas said he hopes he could pitch in the playoffs, but he also said it’s possible the Rockies will shut him down and not allow him to pitch winter ball, as is often his custom.

Righty Juan Rincon, who is on the disabled list with right elbow soreness, had made two strong performances for Colorado Springs on a rehab assignment. Rincon said his rehab term expires Sept. 3, but he is hoping to be restored to the active roster once the limit is raised from 25 to 40 on Sept. 1.
